Interactive Lessons for Engineering; An Example From Elementary Beam Theory.
Bennett, James A.
A series of graphically-oriented computer-assisted instructional (CAI) lessons in elementary beam theory has been developed for an undergraduate course in solid mechanics. The lessons were implemented on the PLATO CAI system at the University of Illinois; the system included a graphical display unit (CRT) and a CDC 1604 computer. The first phase of the lessons was devoted to the presentation of theoretical derivations via a linear program; following this, the students were exposed to programs which drilled them to develop two basic skills for beam stress analysis. These were: 1) the calculation of section properties, and 2) the calculation of internal forces. Students were then given a free-flowing synthesis program which required them to input a beam idealization along with material and cross section dimensions and to produce an acceptable design. Preliminary evaluation of test results indicated that students who used the CAI programs performed slightly better than comparable students who were taught by the lecture method, and that the CAI group took less time to learn the material. The data thus indicated definite promise for increasing learning and decreasing time to criterion through the use of CAI. (PB)
